9 Claims.

My invention relates to improvements in means for use as a ventilatorand a cable attaching bitt or part for ships, boats and the like, andthe same has for its object to provide a simple,

durable and efficient device which may be readily opened for use as aventilator or closed against the access of Water during storms or heavyseas.

Further, said invention has for its object to provide a device of thecharacter specified in which the parts thereof may be readily extendedor collapsed in order to open or close the ventilator.

Further, said invention has for its object to provide a device of thecharacter specified in which one of the parts thereof constituting thebitt or post is of tubular construction forming a portion of theventilator passage extending through the deck and serving as a housingfor other parts of the Ventilator.

Further, said invention'has for its object to provide a device of thecharacter specified in which the ventilator includes telescoping partshaving actuating means for controlling the relative position of theparts.

Further, said invention has for its object to provide a device of thecharacter specified in which the actuated part of the ventilator carriesa closure for effectively sealing the fixed member or housingconstituting the bitt in the closed position of the ventilator.

Further, said invention has for its object to provide a device of thecharacter specified in which the extensible member of the ventilator hasan opening in the wall thereof including a socket for the attachment ofa mouth member constituting a ventilator cowl or hood adapted to bereadily removed when the ventilator is to be closed.

Further, said invention has for its object to '1 provide a device of thecharacter specified in which a sheet metal member or jacket secured tothe deck and embracing and connecting contiguous posts or bitts atpoints above the deck serves to bind the said posts together and tobrace a3 the same, whereby to supplement the post anchorages in the deckin resisting stresses and strains imposed upon the posts by the ropesand cables.

Further, said invention has for its object to provide a device of thecharacter specified in which an insect screen may be employed withoutinterfering with the operation of the device.

Other objects will be in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and Lil ends my inventionconsists in the novel features of construction, and in the combination,connection and arrangement of parts hereinafter more fully described andthen pointed out in the claims.

In the accompanying drawings- Figure 1 is a side elevation of one formof device constructed acording to and embodying my said invention;

Fig. 2 is a plan thereof;

Fig. 3 is an enlarged cross-section thereof on the line 3-3 of Fig. 2;

Fig. 4 is a similar cross-section showing the parts in extended positionwith the removable cowl in position thereon;

Fig. 5 is a cross-section on the line 5-5 of Fig. 4;

Fig. 6 is a perspective of one of the ventilator cowls or hoods, and

Fig. 7 is a perspective of the screen.

Referring to the drawings, the deck or floor of the ship or otherstructure, indicated at I0, is provided with openings ll therethroughreceiving like devices 12 and H each constituting a combined ventilatorand bitt embodying the invention.

Each of the devices l2, lz comprises a tubular member l3, preferablycomposed of cast iron or other metal having openings l4 and 15 at theends thereof, and being of sufficient strength and size to function as apost or bitt for the attachment or securement of the usual cables orropes employed on shipboard. Each of the members I3 is secured withinits opening H by means, such as the flanged rings l6 secured to theopposite faces of the deck and to the member l3 by bolts or othersecuring means H. The member l3 forms a ventilator passage or conduitproviding communication between the outside and the spaces below deck.

The thickened upper margin l8 of the post member I3 is provided with anannular groove or recess I9 in the top thereof adapted to receive thecooperating annular rib upon the inner side of the metal cover 2! in theclosed position thereof as hereinafter described. A transverselydisposed spider 22 is secured within the member I3 near the lower endthereof, and is provided centrally thereof with hub portion or bushing23, preferably of bronze, constituting a threaded nut cooperating with athreaded spindle or shaft 24, also preferably of bronze, secured orswivelled at the upper end thereof to the cover 2|. If so desired, amember 26 of teakwood or other material may be also secured to the topof the metal cover 2! by means of the screw 25 to allow the device to beused as a seat in the closed position of the ventilator.

The cover 2| also serves as a support for the tubular Ventilator member27, composed prefer ably of sheet metal to minimize the weight to belifted, and welded or otherwise secured at one end to the dependingannular rib 28 upon the inner side of the cover 2! which also forms aclosure for the outer end of the member 2?. The member 21 istelescopically received within the fixed member [3 which serves as ahousing therefor and for the spindle 24 in the closed position of theventilator, and said member 21 when extended, as shown in Fig. l,communicates through the open lower end 29 thereof with the passage inthe member I3. The telescoping part 2'! may be readily extended orcollapsed by rotation of the actuating wheel 30 secured to the lower endof the screw spindle 25 below deck. In the closed position of the devicethe parts l9 and 2G interengage to effectively seal the ventilatoragainst access of water. A suitable packing may also be employedtherebetween.

Air is admitted to the member 2? in the extended position thereofthrough a preferably polygonal opening 3! in the wall thereof. ihemember 2! is provided with inwardly directed flanges 32 disposed aboutthe margin of said opening 3| and forming a socket for detachablyreceiving the mouth member or ventilator cowl 33, preferably formed ofsheet metal. The member 33 has a neck portion 36 corresponding in shapewith the socket 32 and adapted to fit the same and a flaring inlet ormouth portion 35. When two or more of the ventilators l2, 12 areassociated as shown, the cowls 33 may be made slightly different in sizeso that they may be nested together when not in use.

It is often desirable to provide means for preventing insects fromentering the ship through the ventilating device, and for this purpose Iprovide the circular screen 35 having the surrounding frame 37 and areinforced opening 38 in the middle thereof. The screen 36 is of a sizeadapted to fit the interior of the tubular member l3, and the opening 38is adapted to receive and fit the lower end of the spindle 25 below thespider 22. The screen 36 is retained in place by the handle 38 which isremovably secured to the spindle by a screw 39 In operation, when theventilator is closed, the screen member rests upon the inturned flange39 at the lower end of the member is. When the ventilator is opened thescreen 36 is engaged by the member 30 and moves up with the screw so asto screen the passage without interfering with the opening operation.

When the devices 52, l2 are employed in pairs, I preferably providemeans 40 for reinforcing, bracing and connecting the projecting portionsof the members i3 at points above their anchorages in the deck. Saidmeans preferably comprises a sheet metal jacket 4!, either in one or twoparts, including a transverse intermediate portion 52 having openings 43therein for receiving the members l3 and the downwardly extendinglateral portions 4 3 terminating in feet 45 in engagement with the deck[0 and secured thereto by the bolts or other securing means 46. Forpurposes of assembly, the jacket 4! may, if so desired, be made in twocooperating, parts ti M having the downwardly directed flanges 37thereon extending longitudinally of the edges at thecentral junctureline 48 thereof. The two parts M and M are secured together at theflanges 47 by the bolts or other securing means 49. By securing thejacket parts together at points below the top 42 thereof provides asmooth surface at the top of the jacket Al and between and around theposts 52, l2 obviating rough or projecting portions at the top liable tocut or fray the ropes or cables.

By my invention I provide a strong, durable device capable of beingemployed as a post or bitt for the attachment of cables, etc. and as aventilator which may be readily opened and closed, and which in theclosed position thereof effectively keeps out the water, and serves tohouse the extensible part thereof.
